What it means for materials suppliers
Why we’re here today
3. Data Collection for Benchmarking
Policy and Legislation:
Executive Order B-30-15
California Transportation Plan 2040
Strategic Management Plan Goal 3 – Sustainability, Livability,
Economy (2015-2020)
Director’s Policies: 30 - Climate Change and 33 - Sustainability
CA Assembly Bill 32 (GHG Reduction), 296 (Urban Heat Island),
262/1817 (Buy Clean CA), CA Senate Bill SB-1

The
Roadmap!
8. Specification language will include EPD requirements for both Buy Clean
California Act (BCCA) and pilot project materials.
Pilot projects will have LUMP SUM bid item for EPDs, Buy Clean California
Act projects will not.
Pilot projects only:
Section 6 “Control of Materials”
Material or Product Material Specifications Applicable Product Category Rule
Aggregatee Section 25, “Aggregate Subbases,” or Section
26, “Aggregate Bases”
ASTM International Product Category Rules for
Preparing an Environmental Product Declaration for
Construction Aggregates: Natural Aggregate,
Crushed Concrete, and Iron/Steel Furnace Slag
Asphalt concretef Section 39-2, “Hot Mix Asphalt” National Asphalt Pavement Association Product
Category Rules for Asphalt Mixtures
Concreteg 1) Section 40, “Concrete Pavement”
2) Section 49-3, “Cast-In-Place Concrete Piling”
3) Section 51, “Concrete Structures” excluding
rapid strength concrete, precast concrete, and
minor concrete uses
North America Product Category Rules for ISO
14025 Type III Environmental Product Declarations
and GHG Protocol Compliant Product ‘Carbon
Footprint’ of Concrete
eFor each subbase or aggregate base used in a quantity of 2,000 cubic yards or more on the project.
fFor each job mix formula used in a quantity of 1,000 tons or more on the project.
gFor each concrete mix design used in a quantity of 500 cubic yards or more on the project.
How will Caltrans collect EPDs?
12. Pilots projects will provide knowledge on compliance
and how to obtain and manage EPD data prior to
statewide implementation
Aggregate, Asphalt Concrete and Concrete EPD Pilot
Projects will start advertising in Spring 2019
EPD data will be submitted electronically through DIME
EPDs support Life Cycle Assessment for our
transportation assets
Go to the METS website to navigate EPDs on
Caltrans projects!
